Are you saying that:

# df -h ==> used MB or GB

then:

# dd if=/dev/hda1 bs=1M count=<used MB or GB> | gzip > hda1-image.gz

then, on the new drive:

# zcat hda1-image.gz | dd of=/dev/hda1 >& /dev/null

won't cut it for you?!?


That one is not good.
As every filesystem I know of fragmentizes its data a part of a file
could physically lay behind the 20th GB. Using your method it would not
be imaged.
